3 VMA Mode

3.4 IQ Waveform Measurement

If there are no active markers, Marker selects Marker 1, sets it to POSition

(Normal) mode, and places it at the center of the display. If the selected marker is

OFF, it is set to POSition mode and placed at the center of the screen, on the trace

determined by the Marker Trace rules.

For details of the POSition, DELTa, and OFF mode options, see "Marker Mode" on

page 747.

3.4.7.1 Select Marker

Sets the selected marker. The term “selected marker” is used throughout this

document to specify which marker will be affected when you change marker

settings, perform a Peak Search, etc.

The Select Marker control appears above the menu panel, indicating that it applies

to all controls in the Marker menu panels. Select Marker is blanked if you select a

tab whose controls do not depend on the selected marker (for example, Counter).

For any menu that includes Select Marker, the first control is always "Marker Time"

on page 745.

Notes The selected marker is remembered even when not in the Marker menu and is used if a Search is done

or a Band Function is turned on or for Signal Track or Continuous Peak

Preset Marker 1

State Saved The number of the selected marker is saved in instrument state

Annunciation Appears in the marker results block label for POSition and Delta markers

3.4.7.2 Settings

The controls on this tab include the Marker active function and a radio button

selection for "Marker Mode" on page 747 (POSition, DELTa, or OFF) for the

selected marker, as well as additional functions that help you use markers.

Marker Time

This is the fundamental control that you use to move a marker around on the trace.

Because it is the default active function in the Marker menu, all you need to do is

press Marker and turn the knob to move the marker left and right on the display.

This is always the first control on any Marker menu page that follows the Selected

Marker.

The SCPI command sets the marker X-Axis value in the current marker X-Axis Scale

unit. The marker that is addressed becomes the selected marker. It has no effect

(other than to cause the marker to become selected) if the control mode is OFF, but

it is the SCPI equivalent of entering an X value if the control mode is POSition or

DELTa.
